I have to say something that if this topic arised than definitely KT should replace with somebody. When Tulsi was newcomer I think nobody questioned or had doubts about her that " replace Smriti with who" . This is 100% sure that KT is 100% ugly with bad acting .there is no comparision between Tulsi and KT . I think delibrately Ekta chose ugly KT becoz She doesn't want anybody to reach Tulsi's Level or skills becoz it will cut down Tulsi's value if somebody is same . 😉
